2026-09-29 Photometric and Spectroscopic Observational Dataset of δ Scuti‑type Pulsating Eclipsing Binary TIC 197757000 doi:10.57760/sciencedb.014bu en This dataset corresponds to the paper TIC 197757000: An Eclipsing Binary System Containing a δ Scuti‑type Pulsating Star with Tidal Synchronization (Yaqup et al., 2026, Research in Astronomy and Astrophysics, 26, 115001).TESS space‑based photometric data: Observations from TESS satellite Sectors 16, 17, 56, 57, 76, 77, 83 and 84, including 120‑s short‑cadence (TSC) data; some sectors also provide 1800‑s long‑cadence (TLC) light curves, with a total observational time span of 211.6 days. Preprocessing including outlier removal, NaN elimination and normalization was performed with the Lightkurve software.PAT‑17 ground‑based photometric data: Observations obtained with the Photometric Auxiliary Telescope‑17 (PAT‑17, 43‑cm aperture) at Nanshan Station, Xinjiang Astronomical Observatory. The telescope is equipped with a QHY4040 sCMOS camera and Sloan‑g, r, i filters. Observations were carried out from BJD 2460237.2 to 2460347.1, yielding 3794 data points in the g‑band, 3759 in the r‑band and 3778 in the i‑band. Raw FITS images were corrected for bias, dark current and flat‑field effects. Aperture photometry was performed using SExtractor, and differential photometry was applied to derive the target light curves.BFOSC spectroscopic data: Low‑resolution spectra obtained with BFOSC (Beijing Faint Object Spectrograph and Camera) mounted on the 2.16‑m telescope at Xinglong Observatory, National Astronomical Observatories of China. The G4 grating was used, covering the wavelength range 3600‑8700 Å at an orbital phase of approximately 0.5. Data reduction included cosmic‑ray rejection, spectral extraction and flux calibration, for the purpose of determining atmospheric parameters of the primary star.
